Archaius is a Java configuration management library that unifies static and dynamic configuration sources into a single API. It supports lock-free property reads, composite configuration layering, and runtime property updates without application restarts.

Use cases

• manage application configuration in Java services
• update config values at runtime without restarting the app
• layer multiple config sources with override precedence
• load properties files with cascading context overrides
• react to configuration changes with change handlers
• integrate config with dependency injection like Guice

When to choose

• you need dynamic, hot-reloading configuration in a JVM application
• you want to combine multiple configuration sources into one composite view
• you're building Netflix OSS-style microservices on the JVM

When to avoid

• you need a simple static config file loader with no dynamic updates
• you're not on the JVM
• you want a config server or centralized config store rather than an embedded library
